Thank, this all looks fine to me.
I subjected this to the same testing I do for each renesas-drivers release.
I have detected no regressions[*].
[*] The only regression I'm aware of is a regression in 4.14-stable, which can
be fixed by "tick/nohz: Prevent bogus softirq pending warning".

Is that something we want to add to LTSI-4.14?

As that is a fix for a regression introduced in v4.14.62, I think it should
be fixed in 4.14-stable instead (and hopefully be fixed automatically in
v4.14.x-ltsi rc2 or final).
